The Mesostigma viride NIES-296 genome sequence and gene models have not been determined by the JGI, but were downloaded from NCBI (GCA_009746045.1, GSE123852) on July 18, 2020. In order to ensure this genome is comparable to those sequenced by the JGI, we applied filters to remove if present: 1) transposable elements, 2) pseudogenes, 3) alternative transcripts and overlapping models, 4) alleles on secondary scaffolds and 5) unsupported short models. This resulted in the removal of 14,453 models and the generation of the FilteredModels1 (GeneCatalog) gene track. All published models are available in the ExternalModels track. Please note that this copy of the genome is not maintained by NCBI and is therefore not automatically updated. In order to allow comparative analyses with other algal genomes sequenced by the JGI, a copy of this genome is incorporated into PhycoCosm. The JGI Annotation Pipeline was used to add functional annotation to the genes.

Mesostigma viride NIES-296

Mesostigma viride (Archaeplastida, Viridiplantae, Phylum Streptophyta, Class Mesostigmatophyceae) is an extant unicellular biflagellate freshwater charophyte algae. Instead of cell wall, M. viride is covered by an outer layer of basket‐like scales. M. viride is one of the earliest diverging members of streptophytes. It is an essential model for understanding the evolution of multicellularity and the origin of land plants. (description courtesy of Zhe Liang)
